Abstract: PURPOSE:To share the same carriage for a floating test as well as a float warrant test for a medium in common and to prevent an error since the test condition is the same by moving the carriage to a float warrant test device while mounting a head after the end of the floating test of the magnetic head is finished and using the test head so as to conduct the float warrant test. CONSTITUTION:When a carriage 13 is moved to a floating test device A, the floating test of a magnetic head H is conducted to obtain a floating quantity data. Then the carriage 13 with the magnetic head H mounted thereon is moved to a floating warrant test device B of a tested medium 12 to use the magnetic head H to conduct the floating warrant test. In this case, the speed of revolutions of the tested medium 12 in the floating warrant test device B is subjected to correction control based on the floating quantity data obtained by the floating test device A. When the test head H is worn and is disabled in use, the carriage 13 is again moved to the floating test device A to conduct the floating test to obtain the test head. Thus, the test condition is identical to the carriage, no error is caused and the condition of the test head at the mounting part is identical. Thus, the factors of error are more reduced.
